From a user account that is a member of the RTCUniversalServerAdmins group (or has equivalent user rights), or assigned to the CsServerAdministrator or CsAdministrator role, log on to any computer that is in the network in which you deployed Lync Server 2013.

Open a browser window, and then enter the Admin URL to open the Lync Server Control Panel. For details about the different methods you can use to start Lync Server Control Panel, see Open Lync Server 2013 administrative tools.

In the left navigation bar, click Security and then click Web Service.

On the Web Service page, and in the search field, type all or part of the name of the policy you want to delete.

In the list of policies, click the policy that you want, click Edit, and then click Delete.

You can delete web service configuration settings by using Windows PowerShell and the Remove-CsWebServiceConfiguration cmdlet. You can run this cmdlet from the Lync Server 2013 Management Shell or from a remote session of Windows PowerShell. For details about using remote Windows PowerShell to connect to Lync Server, see the Lync Server Windows PowerShell blog article "Quick Start: Managing Microsoft Lync Server 2010 Using Remote PowerShell" at http://go.microsoft.com/fwlink/p/?linkId=255876.
